The end of daylight saving is a good time to check your smoke alarm. New Zealand Fire Service risk management officer Phil Faidley says that as well as turning your clock back one hour this Sunday at 3am, you should press and hold your smoke alarm test button to make sure it functions. ‘‘If there is no sound, or it doesn’t sound right, change the battery and try again,’’ Mr Faidley says. ‘‘If it still doesn’t work, then replace it with a new, photoelectric smoke alarm.’’ He says firefighters attend more than 3000 calls to house fires every year across the country, and it is estimated that 80 per cent of these houses do not have a working smoke alarm installed. The New Zealand Fire Service recommends long-life, photoelectric smoke alarms in or near every sleeping area in your home.
